2. Configure the project "HCopy"
You first need to copy the HTKLib folder to the root directory of your solution "HTK-windows", and then copy the file "HCopy.c" in the folder "HTKTools" to the root directory of your project "HCopy".

Right click the project "HCopy", and then click the "Properties" as follows:

In the "Properties" window, you need to add the "HTKLib" folder (or $(SolutionDir)\HTKLib) located in the root directory of your solution, to the "Additional Include Directories":

Then add /D "ARCH=WIN32" to the "Command Line":

3. Add the the files (*.c and *.h) except "HGraf.c" and "HGraf.null.c" in folder "HTKLib" into project "HCopy":

4. Finally, you can build your project "HCopy":

PS: if you want to build HSLab.c, you need to exclude HFB.h and HFB.c;
if you want to build HDecode.c, you need to add an additional command line parameter /D "NO_LAT_LM", and also do not add HLM.h and HLM.c to your project "HDecode".
